WP flank Siya Kolisi has been ruled out of the rest of the season with a broken thumb.

The injury, which was obtained against the Golden Lions on Saturday, requires surgery.

Kolisi had an outstanding Super Rugby season for the Stormers and was included in the 30-man Springbok squad for the Rugby Championship. However, he did not make the match 22 for the Test against Argentina at Newlands, and did not travel with the 26-man squad to Mendoza for the return fixture. That saw him called up to WP’s Currie Cup side.

‘Siya’s injury is the only fresh concern from the weekend and it’s obviously a very big loss for us at this stage of the season,’ said WP coach Allister Coetzee.
